I have noticed that Youtube allows these days server space for long and even longer uploads.
There are, for instance, plenty of Indian films in their entire length (some with subtitles, mostly not).
I briefly searched for some Naheed Akhtar qhazals, since she is well known also for them. And I found two different collections called "Best of Naheed Akhtar vol 1". This one is a modest set 40 minutes long, and compiled mostly (?) of TV and live performances:

The other "Vol 1" takes about four hours to watch, while there is also a stupendous "Vol 2" seven hours long...
(And it doesn't end there. Iqbal Bano, Begum Akhtar, Farida Khanum and several others have also been given their own "theme shows".)
